These files are for Rudder Pedal Extensions for a Van's RV-12 aircraft. The stock pedals use a 1" thick foot pad on the crossbar. The actual additional length is -1" from the size listed on the extension (i.e., 2.5" extension is 1.5" longer that the original). The parts may require post print finishing for the bolt hole and bolt head recess hole depending on your printer setup. I print with 4 perimeters in the slicer to ensure a solid area for any final drilling/sizing. The radius on the curved sections match the Van's OEM parts to ensure the fit is correct and the brake section of the pedal will rotate with no binding.  

The 2" and 2.5" extensions require the Brake Pedal Extensions to be added to keep the foot geometry correct in applying the brakes. The Brake Pedal Extension require a hole to be drilled in the brake pedal tube to attach with an AN3 bolt.

Print with one end on the heatbed, holes will be slightly out of round so ream with a drill bit to final size. Recess hole for attachment bolt is sized for an AN (aircraft spec) bolt head.
